Question Are you supposed to get horrible writes from sata ssd drives when using usb enclosure?

[Sohaib]

Thread title, so i moved my Samsung 870 QVO 4TB from sata to external USB 3.2 10 Gbps enclosure. I am using USB 4.0 cable and connecting it to a USB 4.0 40 Gbps port into my Asus Rog Strix X870e-e Gaming wifi motherboard so i know my PC port or cable isn't a bottleneck. I am using Ugreen 10gbps enclosure which says it supports UASP protocol.
Here are my speeds when i was using internal SATA and external enclosure. Enclosure is basically making the drive into old 3.5" 5400 RPM mechincal drives equivalent.

SATA

USB

Is this the usual behavior when using ssd's with external enclosures or is there something wrong on my side?

 

[helpstar]

update usb drivers, chipset drivers, BIOS of the motherboard

check the SSD with samsung magician, if available update firmware of the SSD

update firmware of the ugreen case if available

is the SATA drive getting too hot? how hot is it while benchmarking?

try a standard USB3 port and cable

did you connect it to the front panel of your case´s USB ports or directly to the motherboard?

most likely the external case is not performing well

Quite possible that write cache is not enabled or simply not available via USB.

When I was looking for M.2 SATA enclosures for use with Raspberry PI, the choice of enclosure made a significant difference. The USB to SATA bridge in the enclosure does make a difference.

I have the latest chipset & usb drivers from asus official motherboard page, also latest bios which currently is 1203.

SSD is using latest firmware as per samsung magician.

have'nt checked if there is a firmware for ugreen enclosure, will look out for it.

idle temps is around 31, according to harddisk sentinel maximum temperature today was 37C so i think way below max limit.

i will try it with usb 3 cable and report back later. i think i have got an extra 10gbps USB C to C cable laying around somewhere.

connected it directly to the motherboard's 40 gbps usb c port.

It would depend on whether you were using the Samsung Magician software and its performance optimizing functions when you calculated the SATA speed. I have one of those ssd's and the speed seems normal for non-Magician performance. I've always thought that's a poor performing drive but I use it since I got it on sale before prices skyrocketed years ago.

install latest drivers from amd, might be newer than from asus homepage

Device manager/disk drives.
Open the usb drive/policies.
There are some options about write caching.

I can testify from personal experience that SSDs in external USB enclosures are not supposed to behave this way.

It just so happens that I've just finished testing my old Samsung 830 128GB via a SATA-to-USB 3.0 adapter. The unit was in constant heavy use since January 2014 and I retired it two months ago only because I thought it was prudent to do so. It's only slightly slower as a USB drive than as an internal one.

I also have an inexpensive external enclosure (not Orico) that's dual compatible with SATA NGFF and NVMe drives. It's only USB 3.2 Gen 2 10Gbps. I get up to ~1GB/s with an NVMe drive in it.
